Reference is made to commonly assigned, co-pending U.S. patentapplication Ser. No. ______ by Dustin L. Winters (Docket 96311) filed ofeven date herewith entitled “System For Managing Privacy Of DigitalImages”, the disclosure of which is incorporated herein by reference inits entirety.

FIELD OF THE INVENTION

The present invention relates to a method for managing a collection ofdigital image files.

BACKGROUND OF THE INVENTION

Today, through use of digital cameras, consumers are able to easilycapture and store large collections of personal digital images. Theseimage collections can be stored either locally on a personal computingdevice or stored remotely on an online photo-management service such asKodak Gallery, which are capable of maintaining digital imagecollections for a large number of users and enable users to share theirdigital images with other users via the interne.

Digital images are composed of pixel data which is used to render a twodimensional digital image on an electronic display or in printed hardcopy form. In addition to pixel data, digital images often furtherinclude metadata which is data related to and associated with thedigital image. Metadata is often useful for organizing and searching ofdigital images. Some metadata can be provided automatically when theimage is first captured by a digital camera device, such as for example,capture date and time metadata. Other types of metadata may includemetadata entered by the user such as a caption or ‘favorite’designation. Other types of metadata may be provided by photo-managementsoftware such as a last edited date and time. Another example ofmetadata is people tag metadata identifying one or more people appearingin the digital image. People tag metadata can be entered either manuallyby a user or automatically by photo-management software, for example byusing facial recognition algorithms.

Another type of metadata which can be associated with digital images islocation metadata, such as longitude and latitude coordinate metadata.Location metadata may similarly be provided at the time the image iscaptured, for example by a digital camera device with a GlobalPositioning System (GPS) sensor. Alternately, a user may manually enterlocation metadata at some time after the image has been captured.Location metadata is also useful for organizing a collection of digitalimages. For example, commonly assigned U.S. Pat. No. 6,883,146 describesa graphical user interface (GUI) system for browsing and retrievingdigital images by location. This patent is incorporated herein byreference in its entirety.

However, some users do not always want their digital images to includelocation metadata. Particularly, a user may wish to not include locationmetadata when sharing digital image files with other users or whenpublishing digital images publicly, for example on an internet website.Users might, for example, want to publish an image captured at theirhome, but not necessarily provide the precise latitude and longitudecoordinates of their home address.

In order to address this concern, some GPS-enabled cameras provide theability to disable the location metadata feature so that metadata is notautomatically saved every time a picture is captured. However, if theuser wants some digital images to include the location metadata andothers to not include the location metadata, the user must remember toturn on and off this setting prior to taking each picture. Alternately,the user may use photo-management software currently available to removethe location metadata prior to sharing or publishing each digital image.However, the user must also remember to do this and may not always beaware which digital images in his or her collection include suchlocation metadata. Alternately, some photo-management services allow auser to specify privacy based on which other users can view locationmetadata for one or more pictures. However, the user must again activelymanage which photos have location information shared for each image orgroup of images where the user wishes to have privacy. As a result,these known methods of addressing the privacy concern with locationmetadata can result in some images undesirably being shared or publishedwith location metadata or some images undesirably captured withoutlocation metadata. An improved system for managing the privacy ofdigital images having location metadata is therefore desired.

SUMMARY OF THE INVENTION

A preferred embodiment of the present invention comprises a method ofstoring a digital image including capturing an image signal from animage sensor and receiving a location signal associated with thecaptured image signal. A digital image file derived from the imagesignal is stored in memory. Metadata derived from the location signal isstored in association with the digital image only if the locationmetadata is determined not to be within one or more predefined exclusionzones. A GPS receiver module can be implemented to obtain the locationsignal. The exclusion zones are also stored in a memory apparatus.Alternatively, the digital image is stored in a second digital memorydifferent from the memory storing the exclusion zones. The digitalmemory can be removable memory.

Another preferred embodiment of the present invention includes a methodof controlling access to a digital image comprising providing to asystem processor a digital image stored in a digital memory, wherein thedigital image is logically associated with capture location data.Exclusion location data is also provided to the processor, which islogically associated with a receiver. The processor then determines arelationship between the capture location data and the exclusionlocation data, and transmits the digital image and the capture locationdata to the receiver if the determined relationship between the capturelocation data and the exclusion location data is of a first type. Secondexclusion location data provided to the processor can be treateddifferently if the processor determined relationship between the capturelocation data and the second exclusion location data indicates that therelationship is of a second type. In that case, only the digital imagewill be transmitted. In the context of a preferred embodiment of thepresent invention, a receiver is typically a requesting node but neednot be a source of a request. Similarly, the receiver can be indirectlyassociated with a requesting user, a “requestor,” communicating arequest message over the network. The request may originate elsewhere inthe network, by a separate requestor, and identify another node as areceiver of the digital image. A node can include a computer, acommunication device, or a human user at the network node who is usingthe computer or communication device. Thus, it should be noted that thereceiving node can be the same node as the requesting node or it can bea different node.

Another preferred embodiment of the present invention includes a methodfor displaying digital images having location metadata associatedtherewith. The method includes retrieving from a memory a digital imagefile associated with a first user and geographic location metadata forthe digital image file. Then, geographic exclusion zones associated withthe first user are retrieved from the memory. Displaying digital imagedata from the digital image file depends on whether the geographiclocation of the location metadata is not within any of the one or moregeographic exclusion zones.

Another preferred embodiment of the present invention includes a methodfor transmitting digital images with location metadata between aplurality of users including proving a database having a plurality ofusers, receiving a digital image file from a first user, receivinggeographic location metadata for the digital image file, receiving oneor more geographic exclusion zones associated with the first user,transmitting digital image data to a second user, and transmitting thegeographic location metadata of the digital file to the second user ifthe geographic location of the location metadata is not within any ofthe one or more geographic exclusion zones. At least a portion of thetransmitted digital image data and at least a portion of any transmittedgeographic location metadata of the digital image file can be stored ona digital electronic storage memory device.

Another preferred embodiment of the present invention includes a methodfor displaying digital images with location metadata, including storingin an electronic memory a digital image file associated with a firstuser, storing in an electronic memory geographic location metadata forthe digital image file, storing one or more geographic exclusion zonesassociated with the first user, transmitting digital image data to acomputer associated with a second user, and transmitting the geographiclocation metadata of the digital file to the computer associated withthe second user only if the geographic location of the location metadatais not within any of the one or more geographic exclusion zones.

Another preferred embodiment of the present invention includes a methodfor displaying digital images with location information, includingstoring in an electronic memory a digital image file associated with afirst user, storing geographic location metadata for the digital imagefile, storing at least one geographic exclusion zone associated with thefirst user, storing a list of users with access rights to the at leastone geographic exclusion zone, transmitting digital image data to acomputer associated with a second user, and transmitting the geographiclocation metadata of the digital file to the computer associated withthe second user only if the geographic location of the location metadatais not within any of the one or more geographic exclusion zones or ifthe second user is among the list of users with access rights to the atleast one geographic exclusion zone.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, some embodiments of the present inventionwill be described in terms that would ordinarily be implemented assoftware programs. Those skilled in the art will readily recognize thatthe equivalent of such software may also be constructed in electronichardware. Because image manipulation algorithms and systems are wellknown, the present description will be directed in particular toalgorithms and systems forming part of, or cooperating more directlywith, the method in accordance with the present invention. Other aspectsof such algorithms and systems, together with hardware and software forproducing and otherwise processing the image signals involved therewith,not specifically shown or described herein may be selected from suchsystems, algorithms, components, and elements known in the art. Giventhe system as described according to the invention in the following,software not specifically shown, suggested, or described herein that isuseful for implementation of the invention is conventional and withinthe ordinary skill in such arts.

A computer program product can include one or more storage media, forexample; magnetic storage media such as magnetic disk (such as a floppydisk) or magnetic tape; optical storage media such as optical disk,optical tape, or machine readable bar code; solid-state electronicstorage devices such as random access memory (RAM), or read-only memory(ROM); or any other physical device or media employed to store acomputer program having instructions for controlling one or morecomputers to practice the method according to the present invention.

The invention is inclusive of combinations of the embodiments describedherein. References to “a particular embodiment” and the like refer tofeatures that are present in at least one embodiment of the invention.Separate references to “an embodiment” or “particular embodiments” orthe like do not necessarily refer to the same embodiment or embodiments;however, such embodiments are not mutually exclusive, unless soindicated or as are readily apparent to one of skill in the art. The useof singular or plural in referring to the “method” or “methods” and thelike is not limiting. It should be noted that, unless otherwiseexplicitly noted or required by context, the word “or” is used in thisdisclosure in a non-exclusive sense.

The term digital image is used herein to include still digital imagefiles or video digital image files. Digital images may further bearranged into groups such as albums or events. These still digital imagefiles, video digital image files, album groups, and event groups, arecollectively referred to herein as digital image assets. Each of thesetypes of digital image assets may have associated metadata entered bythe user or automatically provided by a capture device or otherwiseprovided by photo-management software. For example, an album or eventcollection of digital images may have metadata which describes thedigital images contained within that collection. Such metadata isconsidered as being associated with the album or event collection andtherefore also associated with each of the still digital image files andvideo digital associated with that album or event collection.

The present invention uses location metadata. Location metadata can takea variety of forms including geographical longitude and latitudecoordinates. Location metadata can also take other forms such as astreet address or a place name (i.e. “Rochester, N.Y.”, “YankeeStadium”, etc. . . . ). Location metadata can also take other forms suchas the identity of a nearby fixed point such as a network node, cellularcommunication tower, Radio Frequency (RF) transmitter, or the like.

The preferred embodiments of the present invention operate as part of,or in connection with, a multi-user online photo-management service.On-line photo-management services enable users to share digital imagesover a network such as the internet. Such photo-management servicesstore digital images on a network server. Photo-management services mayalso optionally provide the user with the ability to order hardcopyprints or other photo goods (such as photobooks, calendars, greetingcards, mugs, t-shirts, and the like), although this capability is notrequired to successfully practice the present invention. Kodak Galleryis an example of online photo-management service currently available.Several of the methods of the present invention can also be applied toon-line social network services that enable users to upload and sharecollections of digital media assets with other users. Such socialnetworking services which enable users to manage and share digital mediaassets are herein also considered to be an online photo-managementservice. With such a social networking website, each individual user hasan associated online account that can be linked to accounts for otherusers known to the user. When users upload digital media assets to theirrespective accounts, other users who are identified as “friends” or whoare within a common “network” with the uploading user can view thedigital media assets, depending on any additional sharing or privacyrestrictions. In some cases, the users of such social network sites oronline photo-management services have the option to manually tag thedigital media assets with metadata which identifies persons contained inthe digital media assets, although this ability is also not required forsuccessful implementation of the present invention.

In the preferred embodiments, the online photo-management serviceincludes at least one network server, connected and accessible via theinternet by means of a Uniform Resource Locator (URL). Alternately, theonline photo-management service can be supplied by way of a personalnetwork or intranet or another private, non-public, or privately managednetwork system such as a cellular telephone network.

The userdatabase or image database may include data written on the non-volatiledigital storage memory devices.

One skilled in the art will understand that the user database and imagedatabase could be constructed as a plurality of database tables insingle database or from a plurality of connected databases. Thedatabase(s) could be stored on a single hard drive or multiple harddrives, or could operate on the one or more servers. Preferably thedatabase(s) operate using Structured Query Language (SQL) which ispresently available in many commercial products, such as the MySQLsoftware, or the like. Alternately, one skilled in the art can constructthe database search and retrieval functionality in custom software andcan store the database information in one or more computer files. Suchcustom data storage and retrieval programs are considered a type ofdatabase for purposes of the present invention.

Each user accesses the online photo-management service by way of anaccess device. A wide variety of access devices for connecting to onlineservices which are currently available can be employed, including, butnot limited to; a personal computer (PC) with a modem or network card, amobile phone with internet access, a digital camera device with internetaccess, a digital photo frame with internet access, a video gamingcounsel with internet access, a set-top box or digital media playerdevice with internet access, or the like.

Turning now to FIG. 2, the figure shows an illustration of acommunications device according to multiple embodiments of the presentinvention. Digital camera 100 is in communication with network 200, suchas the internet using the network communication module described above.Communication to the network may be achieved through the use of anetwork service provider (not shown). Online photo-management service300 is also in communication with the network 200. Onlinephoto-management service 300 includes one or more servers havingprocessor(s) 320 (central processing units) and at least one storagememory 330, such as a magnetic hard disk, for executing server programsand functions, for receiving and transmitting network communications,for storing digital images files, metadata, other user information, aswell as any HTML and PHP files needed to access the service. Onlinephoto-management service 300 includes a database 310 for managing aplurality of users and associated digital image files. Database 300preferably includes a plurality of tables for managing users and digitalimages files as will be described in more detail below. Digital camera100 can transmit digital images to the online photo-management service300 by way of network 200.

One or more computer access devices, such as computer access device 400,may also access the online photo-management service 300 by way ofnetwork 200 in order to access digital images stored there. The computeraccess device also includes a processor 410, or central processing unit(CPU), and preferably includes its own storage memory 420, such as ahard drive.

The computer access device also includes a networkinterface unit (not shown) such as a network interface card or wirelessnetwork adaptor for connecting to network 200.

Turning now to FIG. 3, a graphic user interface 500 according to thepresent invention is shown and will now be described with continuedreference to FIG. 1 and FIG. 2. Graphic user interface is provided toenable the user to enter one or more geographic exclusion zonesaccording to the present invention. Graphic user interface 500 may begenerated in the digital camera 100 and displayed on the display 140 ofthe digital camera. In an alternate embodiment the graphic userinterface 500 may be generated by the online photo-management service300 and made available to a user over network 200 through, for example,a web-browser interface. In yet another alternate embodiment, thegraphic user interface may be generated by software loaded on to apersonal computer which is either connected to digital camera 100directly, can receive removable memory cards from digital camera 100, orcan communicate with digital camera through a network such as computeraccess device 400 connected to network 200.

Graphic user interface 500 contains a map region 510. Map region 510displays maps which may be either preloaded into memory or may bedownloaded from an online map service provider over the network. Graphicuser interface 500 also contains several controls to enable the user tonavigate to different locations such as scroll arrows 520, zoom in andout controls 530, pan control 540, and location search input box 550.The graphic user interface 500 enables the user to designate one or moreexclusion zones such as exclusion zone 560 a, for example designatedaround the user's home, and exclusion zone 560 b for example designatedaround a nearby school. Exclusion zones may be designated at varyingsizes and shapes and it is not necessary that all exclusions be visiblesimultaneously on the map region 510. Designation control 570 a,designation control 570 b, and designation control 570 c are exemplarycontrols for designating round, rectangular, and free-form shapedexclusion zones respectively. The user selects one of these controls andthe draws the exclusion zone on the map region 510 using an inputdevice, such as a touch screen or the like. Deletion control 570 x isprovided to enable the user to delete previously created exclusion zonesas desired.

In order to facilitate the entering of rectangular or free-form shapedexclusion zones, it is preferable that the map region 510 be made todisplay a flat representation of the Earth, without wrapping around the180 degree meridian including the north and south pole. For example, themap region will not scroll ‘up’ past the north pole, ‘down’ past thesouth pole, or left or right past the 180 degree meridian. In this way,there is no ambiguity as to which area specified by the user is the‘inside’ area versus the ‘outside’ area for free-form shapes. This maparrangement will be referred to herein as a “non-wrapping map”arrangement. This further facilitates later calculations whendetermining whether a given point is inside or outside the exclusionzone. Alternately, a continuous globe shaped map region may be used.This alternate arrangement will be referred to herein as a “wrappingglobe arrangement”. In this case, the user should be asked as to whichregion is the inside of the region, for example, by asking the user toselect a point within the region. Even in this case, it is preferablethat no side of the polygon be allowed to exceed half of thecircumference of the Earth.

Turning now to FIG. 4 and with reference to FIG. 1 to FIG. 3, a firstembodiment of the present invention will now be described. In this firstembodiment, digital camera 100 stores a list of exclusion zones ininternal storage memory 125. The exclusion zones are created usinggraphic user interface 500 as previously discussed. This can be doneeither on the camera using the camera display 140 and processor 110, oron a personal computer or on the photo-management service and loadedonto digital camera 100. The resulting exclusion zones are preferablystored in a table in internal storage memory 125. This table isillustrated here as table 1:

TABLE 1 In-Camera Exclusion Zone List Table ZoneID Caption CenterPointRadius NW SE Freeform 1 Home 43.152421, −77.579979 5 2 School 43.157980,−77.601628 3.5 3 Grandma's House 43.204381, −77635504 43.201842,−77.626791 4 Work 43.161828, −77.620030; 43.158682, −77.615778;43.156601, −77.620723; 43.159040, −77.623894The example of table 1 shown here is populated with four exemplaryrecords of data for purpose of illustration. The exclusion zone listtable includes a “ZoneID” primary key field for uniquely identifyingeach exclusion zone. The table also includes a “Caption” field to allowthe user to identify each exclusion zone. The “CenterPoint” field and“Radius” field are used to store the center-point geographic coordinatesof exclusion zones defined using designation control 570 a. Alternately,the “NW” and “SE” fields are used to define the northwest and southeastcoordinates of a rectangular exclusion zone defined using designationcontrol 570 b. Finally, the “FreeForm” field is used for storing aseries of coordinates of a polygonal shaped exclusion zones definedusing designation control 570 c. In the alternate “wrapping globearrangement” previously described, the “CenterPoint” field could alsoalternately be used for free-form and rectangular exclusion zones todefine a point within the exclusion zone.

According to the first embodiment of the present invention, digitalcamera executes process 600 of FIG. 4 when capturing a digital image.Process 600 includes step 610 where a digital image signal is capturedusing image sensor 160. A location signal for the captured digital imageis read at the time of capture per step 620 using GPS receiver module170 and is stored in internal memory 130. In step 630 the digital imagesignal is converted into a digital image file by processor 110 andstored in memory, such as removable memory card 120. In step 640 theprocessor loads the exclusion zone list shown in table 1 from internalstorage memory 125. In step 650 the location signal acquired during step620 is compared to each of the exclusion zones loaded during step 640.

For purposes of determining if the image location is within a circularexclusion zone, the Haversine formula (see Equation 1 below) forcalculating a great circle distance can be used. This simplified formulaignores altitude or depth, which are also not recorded as metadata inpreferred embodiments thereby reducing the amount of data which needs tobe stored. Therefore, a constant altitude, such as an approximate sealevel is assumed. In this case the average radius of the Earth ofapproximately 6367.5 km can be used. This can result in small inaccuracies when calculating distance, however, such inaccuracies aresmall enough to be neglected by the users for purposes of the presentinvention. The simplified equation also assumes that the Earth isperfectly spherical, ignoring the fact that the Earth's radius isslightly larger at the equator than at the poles. This assumptionsimplifies the processing thereby improving speed of the processing andreduced storage space for the processing instructions. Other knownformulas for calculating distance can be employed by one skilled in theart, including the spherical law of cosines. Alternately, more complexembodiments of the present invention can be implemented by one skilledin the art by recording altitude and accounting for altitude in thedistance equation and/or by using non-spherical Earth models.

$\begin{matrix}{d = {2 \times R \times {\arcsin \left( {\min \left( {1 \cdot \sqrt{\begin{matrix}{{\sin^{2}\left( \frac{{lat}_{2} - {lat}_{1}}{2} \right)} + {{\cos \left( {lat}_{1} \right)} \times}} \\{\cos \left( {lat}_{2} \right) \times {\sin^{2}\left( \frac{{lon}_{2} - {lon}_{1}}{2} \right)}}\end{matrix}}} \right)} \right)}}} & {{Equation}\mspace{14mu} 1}\end{matrix}$

In Equation 1, lat1 and lon1 are the latitude and longitude respectivelyof the of the exclusion zone center point, lat2 and lon2 are thelatitude and longitude respectively of the location of the digitalimage, and R is the radius of the earth or 6367.5 km. Longitude andLatitude are preferably converted from degrees to radians. The minimum(“min”) function assures that the arcsine function is not provided witha value greater than 1. The distance returned by the equation iscompared to the specified radius of the exclusion zone from table 1 andif less than said radius, the location is considered to be within theexclusion zone.

For rectangular exclusion zone, the calculation is simply determined bywhether the longitude of the location of the digital image is betweenthe longitude of the NW and SE coordinates of the rectangular exclusionzone and the latitude of the location of the digital image is betweenthe latitude of the NW and SE coordinates of the rectangular exclusionzone. It should be noted that these ‘rectangular’ exclusion zones onlyappear rectangular when viewed on a flattened display map but areactually relating curved geographical surfaces.

For freeform polygon shaped exclusion zones, determining if the locationis within the polygon can be achieved using known methods of determiningif a point is within a polygon based on the Jordan curve theorem. Thesemethods involve counting how many edges of the polygon are crossed by aline starting from the location of the digital image to a referencepoint. For the non overlapping map arrangement previously described, thepath between the digital image location and a reference point at thenorth pole (90,0) may be used. Crossing an even number (including zero)of edges indicates that the location is outside of the exclusion zone,while crossing an odd number of edges indicates that the location iswithin of the exclusion zone. Alternately, for the wrapping globearrangement, the number of edges crossed for a line traveling betweenthe location of the digital image to the reference point within theexclusion zone will be an even number (including zero) if the locationis within the exclusion zone, or an odd number of crossing if thelocation is outside of the exclusion zone.

For the present invention, the occurrence of an edge crossing can bedetermined using the following procedure. Each edge of the polygon withits starting and ending point forms a great arc, which is a portion of agreat circle around the sphere. Likewise, the great arc between theimage location and the reference point is a portion of another greatcircle. The intersections of these great circles are determined usingknown mathematical techniques. This will result in two intersectionpoints which are antipodal. Next, it is calculated whether either ofthese intersection points are contained within both of the great arcs.Since the polygon sides are preferably limited to less than half thecircumference of the Earth as previously described, only one of theantipodal intersection points can be on the great arc path of the edge.One technique for performing this test is to calculate the great arcdistance using the Haversine formula, as described above, between thegreat circle intersection point and the start and end points of eacharc. If each of these great arc distances are less than the total greatarc distance of the entire arc and also less than one half of thecircumference of the earth, then the intersection point lies within thegreat arc. If the intersection point is within both great arcs, thenthat edge is crossed. In the special case where an intersection point isexactly equal to a polygon vertex, then it is unknown as to whether theimage location to reference point line crosses into the polygon or not.One method to work around this case is to temporarily shift the polygonvertex by a small amount (such as 0.000001 degrees) when an intersectionwith a vertex is detected and recalculate the intersection point. Theprocess is repeated for all edges of the polygon and a total number ofcrossings is calculated. Depending on whether an even or odd count ofintersections are calculated, as described above, the relative positionof the digital image location within the polygon is returned.

Decision block 650 is then executed. If the location signal is found tobe within any of the exclusion zones, the process ends. If the locationsignal is not within any of the exclusion zones, the process continuesto step 670. In step 670, the location signal is converted intogeographic location meta-data information and is associated with thedigital image by adding it to the digital image file stored during step630. Alternately, the geographic location meta-data can be stored andassociated with the digital image by creating a separate table ordatabase of meta-data which is stored separately from the digital imagefile. By executing process 600, geographic location meta-data is notstored for digital images captured in one of the exclusion zones therebyenhancing the privacy of the user.

Turning now to FIG. 5 and with reference to FIG. 1 to FIG. 3, a secondembodiment will now be described. In the second embodiment, digitalimages files owned by an owner user are shared with a receiving useraccording to process 700 and is executed using an onlinephoto-management service, such as online photo-management service 300.Steps of process 700 executed in connection with the on-linephoto-management service may be constructed by one skilled in the artusing combinations of Hypertext Markup Language (HTML), PHP scripts,Java scripts, and the like.

Process 700 begins with step 710 where the digital image files arestored on the storage memory 330 of the server(s) of onlinephoto-management service 300 and associated in the database 310 with anowner user who uploaded or is otherwise assigned ownership of thedigital image files. The digital image files are, for example, receivedthrough the network by the online photo-management service from theowner user who captured the digital image using a digital camera device.This association is accomplished with a database table shown here astable 2.

TABLE 2 Digital Image File Association Table UserID FileID FileNameUser01 1 0000001.jpg User01 2 0000002.jpg User01 3 0000003.jpg User01 40000004.jpg User01 5 0000005.jpg User02 6 00000F9.jpg User02 700000FA.jpg User03 8 00001C2.jpg

The example of table 2 shown here is populated with eight exemplaryrecords of data for purpose of illustration. Table 2 includes a field“UserID” which identifies an owner user for each digital image file.Additional information about each user may be stored in another databasetable, including information such as password, first and last name, andthe like. Table 2 also includes a field called “FileID” which is aunique identifier produced by the database for each digital image file.Table 2 also includes a field called “FileName” which provides fileinformation for each digital image file. This may include a simple filename, or a full path and file name, or another reference name or number.Various forms of file information and storage structure may beimplemented by one skilled in the art. For example, the actual file nameor path on the server may be composed of a combination of the UserID andfilename such as “/user01/0000001.jpg”.

In Step 710, metadata, including location metadata if available, is alsostored in the database. The metadata is also preferably received by theonline photo-management service from the owner and may be transmittedalong with the digital image file, for example if automatically providedby a digital camera device, or it can be manually entered directly intoan html web page file of the online photo-management service at a latertime. Metadata can be stored in one or more tables such as table 3 shownhere:

TABLE 3 Metadata Storage Table FileID MetaDataName Value 1 Date PictureTake Apr. 14, 2010 18:56 1 Equipment Make EASTMAN KODAK COMPANY 1 CameraModel KODAK EASYSHARE Z1012 IS DIGITAL CAMERA 1 GPS Latitude   43.1212671 GPS Longitude −77.640319 2 Date Picture Take Apr. 15, 2010 17:21 2Equipment Make EASTMAN KODAK COMPANY 2 Camera Model KODAK EASYSHAREZ1012 IS DIGITAL CAMERA 2 GPS Latitude   43.258718 2 GPS Longitude−77.604464 3 Date Picture Take Apr. 17, 2010 10:51 3 Equipment MakeEASTMAN KODAK COMPANY 3 Camera Model KODAK EASYSHARE Z1012 IS DIGITALCAMERA 3 GPS Latitude   43.208034 3 GPS Longitude −77.622327

The example of table 3 shown here is populated with fifteen exemplaryrecords of data for purpose of illustration and simplicity. Additionalmetadata fields beyond those shown may also be recorded. Table 3includes a field for the “FileID” the digital image files which is thesame as the “FileID” previously associated in table 2 with an owneruser. Table 3 also includes a field for “MetaDataName” which identifiesa label for each metadata item. FileID and MetaDataName together formthe primary keys for this table. Table 3 also includes a field titled“Value” for storing the value of each metadata item. Metadata itemshaving the label “GPS Latitude” and “GPS Longitude” constitute thelocation metadata. In an alternate embodiment, the metadata may bestored in other ways than in a table form. For example, the metadata maybe stored within the digital image file. If written within the digitalimage file, portions of the metadata such as the values for GPSLongitude and GPS Latitude will need to be deleted or cleared prior totransmitting the digital image file in certain circumstances asdescribed later. In yet another alternate embodiment, the metadata maybe stored in a combination of table form and file form.

Process 700 continues with step 720, where a request is received by thephoto-management service from a requesting user requesting that adigital image stored in the database be shared with a receiving user.The owner user, requesting user, and receiving user may be threedifferent users. Alternately, the requesting user may be the same as theowner user. Alternately, the receiving user may be the same user as therequesting user, or it may be a different user.

For example, according to this second embodiment, the request may comedirectly from the receiving user who has logged in to onlinephoto-management service and has requested access to digital imagesowned by another user (the owner user). The request is received, forexample, via a form or control in a web page encoded as a HypertextMarkup Language (HTML) file stored on the photo-management serviceserver which is being accessed by the requesting user. The request maybe either for a single image such as 0000001.jpg owned by user01 or fora plurality of images such as all images owned by user01.

Process 700 then continues with step 730 where the received request isthen converted into a query on the server to retrieve and load intomemory location metadata for each of the requested images, from thedatabase 310. This operation may be achieved by executing SQL queriesusing a server side process, for example, using a PHP scripting languagefile.

Step 740 is performed where the digital image owner's exclusion zonelist is loaded. The exclusion zones are also stored in database 310using a table for managing exclusion zones such as shown here in table4:

TABLE 4 Online Photo-Management Service Exclusion Zone List Table UserIDZoneID Caption CenterPoint Radius NW SE Freeform User01 1 Home43.152421, −77.579979 5 User01 2 School 43.157980, −77.601628 3.5 User013 Grandma's House 43.204381, −77635504 43.201842, −77.626791 User01 4Work 43.161828, −77.620030; 43.158682, −77.615778; 43.156601,−77.620723; 43.159040, −77.623894 User02 5 Zone 1 43.070148, −772824210.5 User02 6 Zone 2 43.091352, −77544895 0.5 User03 7 Home Zone43.161562, −77.443662 20

The example of table 4 shown here is populated with seven exemplaryrecords of data for purpose of illustration. Table 4 is similar to table1 of the first embodiment and includes the same fields as previouslydescribed for table 1 as well as an additional field titled “UserID”.The UserID field stores information for which user owns each of theexclusion zones thereby enabling the table to store exclusion zones fora plurality of users which access and store images with thephoto-management service. “ZoneID” continues to service as primary key.Alternately, this table could be constructed by one skilled in the artsuch that UserID and ZoneID together serve as primary keys.

The exclusion zones of table 4 are preferably previously populated byeach owner user using a graphic user interface such graphic userinterface 500 previously shown. In this case, the graphic user interfaceis preferably displayed using an html web page operated by the onlinephoto-management service 300 and is accessed, viewed, and operated byeach owner user using a computer access device connected to the network.

During step 740, the exclusion zones for the owner user of the digitalimage file(s) which have been requested by the requesting user areloaded using an SQL query. This is done using a server side process,such as with a PHP script, so that the exclusion zone information is notvisible to the requesting user.

Process 700 continues with step 750 where the location metadata loadedduring step 730 is compared to the exclusion zones of the owner userloaded during step 740. Decision block 760 is then performed todetermine if the location of the digital image is within any one or moreexclusion zones of the owner user. If decision block 760 returns a truevalue, process 700 skips to step 780. In step 780 the digital image fileis transmitted without location metadata to the receiving user, forexample by rendering output HTML including a reference to the digitalimage file on the server which is displayed in a browser on a personalcomputer of the receiving user. If in the alternate embodimentpreviously described where the location metadata is stored in thedigital image file, the location metadata is removed or cleared prior totransmitting the digital image file here in step 780.

If according to decision block 760 the location of the requested digitalimage is not within an exclusion zone, then data from the digital imagefile and location metadata is transmitted to the receiving user in step770. The entire digital image file, or data derived from the digitalimage file such as reduced resolution version of the digital image canbe transmitted. The transmission occurs by outputting the digital imagefile (or a derived digital image file) and location information to oneor more HTML documents which are transmitted from the server across thenetwork to the receiving user for display on electronic display deviceof the receiving user's personal computer or network access device. Thelocation metadata and digital image data can be transmitted in separatesteps, for example by including the digital image file with one HTMLdocument and including the location metadata with a different HTMLdocument. Transmission of the location metadata can also occursimultaneously with the transmission of the digital image file byappending the location metadata to the digital image file.

In step 770 the location metadata is displayed to the receiving user.This display step can occur in a variety of different forms. Forexample, the location information can be output to an HTML document intext form viewable to the receiving user. Alternately, the locationmetadata can be displayed in graphic format by plotting an icon on a mapuser interface within the output HTML document, such as that currentlyprovided by Google Maps (R) or similar services. The location metadataand digital image data can be displayed together in a single HTMLdocument or separately in multiple HTML documents.

A useful graphic interface useful for displaying the location metadatain map form is shown in FIG. 7 as graphic user interface 900. Graphicuser interface 900 can be encoded within an HTML web page for display onthe receiving user's personal computer or it may be generated bysoftware resident in the receiving user's computer which receives thelocation metadata from the online photo-management service 300. Graphicuser interface 900 contains a map region 910. Map region 910 displaysmaps which may be either preloaded into memory or may be downloaded froman online map service provider over the network. Graphic user interface900 also contains several controls to enable the user to navigate todifferent locations such as scroll arrows 920, zoom in and out controls930, pan control 940, and location search input box 950. Graphic userinterface 900 also contains image location icons 960 which arepositioned in various locations in map region 910 and represent retrievedigital image with location metadata corresponding to that position.Image location icons 960 are shown represented as squares in FIG. 7 forpurpose of simplicity in illustration but may actually be digital imageicons showing a smaller (thumbnail) view of the represented image.Alternately, image location icons 960 may be a graphical icon such as acamera picture, postcard picture, push-pin picture, or the like. Imagelocation icons 960 can represent a single digital image and when theicon is activated by clicking or double clicking with an input device,the represented image is retrieved and displayed. Alternately imagelocation icons 960 can represent a group of digital images having thesame location or a proximate location. In this case activation of theimage location icon causes a zooming operation of map region 910 on thatlocation, retrieves and displays the represented digital image(s) orboth by detecting one of a click or a double click on the icon from aninput device. As previously described, digital images with locationmetadata representing a location within an exclusion zone of the owneruser are not represented on the graphic user interface 900 as viewed bythe receiving user.

Returning to FIG. 5, process 700 has thus far been described as operatedusing photo-management service, however, process 700 may also beexecuted in several alternate embodiments which will now be described.In an alternate embodiment to the second embodiment, process 700 can beexecuted on a personal computer having photo-management software loadedlocally and connected to a network, such as computer access device 400connected to network 200. In this alternate embodiment, the owner useris the same as the requesting user and is operating the personalcomputer. The owner user stores digital images with location metadata onthe personal computer (step 710) which are associated with the owneruser by the fact that they are stored on a computer associated with theowner user or with a user profile on the computer associated with theowner user. A request is received by the photo-management software thata digital image be transmitted to a receiving user (step 720) forexample by requesting that an email containing the image be transmittedto the receiving user. The location metadata and exclusion zone listsare loaded in steps 730 and 740 respectively. The exclusion zone list isstored on the local personal computer using table 4 previouslydescribed. Steps 750 and 760 operate as previously described. If theimage location is within an exclusion zone, then the digital image fileis transmitted, for example as an email attachment, without any locationmetadata written in the digital image or in the email which is thendisplayed on a computer of the receiving user per step 780. If the imagelocation is not within an exclusion zone, then the digital image file istransmitted, for example as an email attachment, with location metadatawritten in the digital image or in the email which are then both thendisplayed on a computer of the receiving user per step 770.

In yet another alternate embodiment to the second embodiment, process700 can be executed directly on a digital camera device connected to anetwork such as digital camera device 100 connected to network 200. Inthis alternate embodiment, the exclusion zone list is stored with theinternal storage memory 125 of the digital camera device. The digitalimage is transmitted to a receiving user via Multimedia MessagingService (MMS), email or the like along with the location metadata onlyif not located within an exclusion zone per decision block 760.

Turning now to FIG. 6 and with reference to FIG. 1 to FIG. 3, a thirdembodiment will now be described. The third embodiment is implementedaccording to process 800. In the third embodiment, like the secondembodiment described above, digital image files owned by an owner userare shared with a receiving user. In the third embodiment, differentreceiving users are either provided or denied access to locationmetadata depending on the preference of the owner user.

Process 800 begins with step 805 where digital images files havingassociated location metadata are stored on the storage memory 330 of theserver(s) of the photo-management service 300 and associated in thedatabase 310 with an owner user who uploaded or is otherwise assignedownership of the digital image files. This storage and association maybe accomplished as described above in the second embodiment using tablessuch as table 2 and table 3.

Process 800 continues with step 810, where a request is received by thephoto-management service from a requesting user requesting that adigital image stored in the database be shared with a receiving user.Again, the owner user, requesting user, and receiving users may be threedifferent users or the receiving user may be the same as the requestinguser or the requesting user may be the same as the owner user. Aspreviously described in the second embodiment, the request is received,for example, via a form or control in a web page encoded as a HypertextMarkup Language (HTML) file stored on the photo-management serviceserver which is being accessed by the requesting user.

Process 800 then continues with step 815 where the received request isthen converted into a query on the server to retrieve and load intomemory location metadata for the requested digital image from thedatabase 310. This operation may be achieved by executing SQL queriesusing a server side process, for example, using a PHP scripting languagefile.

Process 800 then executes step 820 where an access rights list isloaded. Access rights are a list of users or groups of users who arepermitted to receiving location metadata for digital images locatedwithin an exclusion zone of the owner user. Access rights are preferablypreviously established by the owner user and stored in a table on thestorage memory 330 of the server(s) of the online photo-managementservice 300 in a table such as table 5 shown here:

TABLE 5 Access rights list table OwnerUser PermittedUser User01 User02User01 User03 User02 User01 User02 User04 User04 User05

Table 5 stores the access rights for all users of the onlinephoto-management service using two fields; an “OwnerUser” and“PermittedUser”. Table 5 is populated with exemplary data records forpurpose of illustration of the present invention. For example, “User02”is permitted to receive location meta-data from digital images locatedwith an exclusion zone of the “User01”. “User01” has also been givenaccess rights to receive location meta-data from digital images locatedwith an exclusion zone of the “User02”. “User04” has also been givenaccess rights to receive location meta-data from digital images locatedwith an exclusion zone of the “User02” but “User02” has not been givenaccess rights receive location meta-data from digital images locatedwith an exclusion zone of the “User04”. In an alternate embodiment,groups of users such as “Friends”, “Family”, “Coworkers”, etc. can beestablished and given access rights. In yet another alternateembodiment, access rights may be established differently for eachexclusion zone, for example by instead using a table with the fields“ZoneID” and “PermittedUser” to define which users are permitted to viewimages in each zone. The zones were previously also associated with anowner user in Table 4. Combinations of these alternate embodiments mayalso be applied.

During step 820, the access rights for the owner user of the digitalimage file(s), which have been requested by a requesting user, areloaded using an SQL query. This is done using a server side process,such as with a PHP script, so that the exclusion zone information is notvisible to the requesting user.

Decision block 825 is then executed where the access rights for thereceiving user to the location metadata of digital images withinexclusion zones of the owner user are determined. If the receiving useris listed in table 4 as having access rights to receiving locationmetadata of digital images within exclusion zones of the owner user, theprocess 800 skips to step 850, where the digital image file and locationmetadata are transmitted and displayed to the receiving user, forexample by generating one or more HTML output documents with the digitalimages and a map interface such as graphic user interface 900 of FIG. 7.If however, the receiving user is not listed in table 4 as having accessrights to receiving location metadata of digital images within exclusionzones of the owner user, then process 800 proceeds to step 830.

In step 830, the exclusion zones for the owner user of the digital imagefile(s) which have been requested by the requesting user are loadedusing an SQL query. The exclusion zones are established as previouslydescribed in the second embodiment using a table such as table 4.Loading is done using a server side process, such as with a PHP script,so that the exclusion zone information is not visible to the requestinguser. Next, step 835 is performed where the location metadata loadedduring step 815 is compared to the exclusion zones of the owner userloaded during step 830. Decision block 840 is then performed todetermine if the location of the digital image is within any one or moreexclusion zones of the owner user. If decision block 840 returns a truevalue, process 800 skips proceed to step 845 where the digital thedigital image file is transmitted without location metadata to thereceiving user, for example by rendering output HTML including areference to the digital image file on the server which is displayed ina browser on a personal computer of the receiving user. If locationmetadata is stored in the digital image file, the location metadata isremoved or cleared prior to transmitting the digital image file here instep 845. If, on the other hand, according to decision block 840 thelocation of the requested digital image is not within an exclusion zone,then the digital image file and location metadata is transmitted to thereceiving user in step 850, for example by generating one or more HTMLoutput documents with the digital images and a map interface such asgraphic user interface 900 of FIG. 7.

The invention has been described in detail with particular reference tocertain preferred embodiments thereof, but it will be understood thatvariations and modifications can be effected within the spirit and scopeof the invention.
